Summary:A downhole device shifts a component from a first state to a second state. The device includes a body having the component in a bore thereof and an annular space formed within an inner and outer wall of the body. The annular space includes a first fluid chamber in fluid communication with the bore at a first location and with a pressure transducer at a second location, the transducer constructed and arranged to measure pressure of the fluid and provide a signal to circuitry controlling a valve upon reception of a predetermined fluid pressure pulse sequence. When the pulse sequence is delivered, the valve opens, placing a source of pressurized fluid in communication with an actuator that shifts the valve.
